WILLIAM HEAP, OF OWEN sOUND, ONTARIO, cANADA.

APPARATUS FOR OPERATING DRY-EARTH CLOSETS.

SPECIFICATION forming part of Letters Patent No. 327,266, datedSeptember 29, 1885.

Application filed January 23, 1885. (No model.) Patented in CanadaNovember 8, 1884, No. 20, 537.

To all whom it may concern.-

Be it known that I, WVILLIAM HEAP, of the town of Owen Sound, in thecounty of Grey, in the Province of Ontario, Canada, have inventd certainnew and useful Improvements in the Apparatus for Operating Dry-EarthClosets, of which the following is a specification.

The invention relates to earth-closets, and it consists in the peculiarcombinations and the construction and arrangement of parts hereinafterdescribed and claimed.

Figure 1 is a perspective view of my improved earth-closet, a portion ofthe woodwork being broken away to expose the part immediately connectedwith my invention. Fig. 2 exhibits alternative form ot'levers and weightfor throwing forward the pivoted earth-hopper.

A is the earth-hopper, pivoted at its top to the frame 13, and having ascoop-shaped bottom, O.

D is a rod connected at one end to a bar attached to the hopper A, andat its other end to one arm of the bell-crank E, which is pivoted on theframe F, and has attached to its other arm a weight, G. which weight iscalculated to be sufficiently heavy to hold forward the bottom of thehopper A and support the back of the seat H at the angle indicated, thesaid back being connected to the hopper A by the lever I, which ispivoted on a rod, J, and has the end which presses against the hopper Aprovided with a friction-roller, a, the other arm of the lever I beingconnected to the seat H by the rod K, as shown in Fig. 1. When the backof the seat is pressed down, the action of the lever I will naturallypush back the bottom of the hopper A, and as the weight G is connectedto the hopper A, as already described,the instant that the forwardpressure is removed from the seat H the action of the Weight G causesthe hopper A to spring forward, the earth by this rapid jerking movement being thrown out of the scoop-shaped bottom 0. v

I should mention here that the frictionroller (It allows the lever I topush back the hopper'A with but little force, and as the leverage of thebell-crank E assists in the raising of the weight G a very lightpressure on the back of the seat H is sufficient to push the hopperback.

In Fig. 2 I- show an alternative form of weight and lever for throwingforward the hopper A. In this form the rod D is pivoted to the frame Fat b, and is connected to the rod attached to the hopper Aby the link d,the weight G being placed near the connection between the rod D and linkd.

As the operation of earthclosets is well understood, and as I do notclaim anything peculiar in its general principle, I need not enter intoa detailed description of its operation.

I am aware of the English Patent N 0. 3,760 of 1872, and United StatesReissued Patent No. 4,138, and make no claim to the constructions showntherein as forming part of my invention.

\Vhat I claim as my invention is- 1. In an earth-closet, thecombination,with the frame B, pivoted hopper A, and the seat H, of therod J, the lever I, pivoted on said rod, the rod K, connecting one armof said lever with the seat, weight G, and intermediate connectionsbetween said weight and hopper, substantially as described.

2. The herein-described earth-closet, consisting of the frame B, thepivoted hopper A, the rod J, the lever I, pivoted on said rod, thefrictionroller a, carried by one arm of said lever, the rod K,connecting the other end of said lever with the seat, the bell-cranklever E, pivoted to the frame, the rod D, connecting one arm of saidlever with the hopper, and the weight G, attached to the other arm ofsaid bell-crank, all combined, arranged, and operating substantially asshown and described. and for the purpose specified.
